Is there an "update path" to CS3 version or do I need to purchase a new one?
Secondly and more importantly where could I find more information on the settings in the Negative mode.
I have followed your advice in photographing my B&W negatives with a slide copier and getting much better result than with my flat bad Epson scanner. More detail and less scratches but processing them is a bit of a puzzle. For instance what is the “negative range" and "negative curves" and how do they interact? What would be a recommended workflow etc.
Having tried other methods yours is by far the best but I am at a bit of a loss. Your help would be much appreciated.
